Zlo. all whom it may concern;

Be it known that I, CLARENCE HANCOCK, a .Subieet of the King ot Great Britain, re.- siding at Letchworth, in the county of Hertfordshire, England, have invented Cartan new `and useful Improvements in. Heating Apparatus, et which the Jfollowing is a spectcatiaii- A This invantien relates to .improved means ,far heating aard-@.11` prapaeatiae frames, faster mothers and the like, which have eornpartments requiring t0 be kept at dit, ferait temperatures `It is impor-tant apparatus of this kind to provideJ .an evenly distributed gentle. heat of the degree required so that the seedlings, in the case of a propagating frame, or the newly hatched Chickens, in. the CaSe of a foster mother, may enjoy as nearly as pos? sible the proper natural temperature cou.- dtons.,

One of the Objects ot the present invention is to providein a single propagating frame or' foster mother having two or more compartments side by side, a ,self contained heating unit ormedof a number of; elements of different haat. radiating capacity, one af which at least is in the form of a. fiat tank, so that aaentle haat may be provided uniformly over the Whole area` @if 01.1.@ @repart-ment The heating unit @an be slid endwise aS a Whole, inta the frame or the like .SQ that the Several elements lie, respectively, the compartments which they are required' to heat.' With this. arrangement two or moreV chambers Can be aenstantly kept at different temperatures, SQ that,

Where the invention ia embodied aplopagation frame, seedlings which have just bef gun to shoot may be moved from the warmest chamber into an adjoining chamber having a lower temperature; `or where the invention is embodied in a foster mother, one chamber may be kept warm enough for the day old chicks whilen an adjoining chamber is warmed sufficiently to care for the chicks after they are a few days old, or at any rate during the day time.

'A further object is to provide a heating unit of the character mentioned which can be heated from the exterior of the frame or the like by any suitable source of heat, for examble a lamp.

The invention is illustrated in the @0.00mpanying drawings l in which,

Figures 1 and 2 are, respectively, a, sectional plan and a front elevation `of the iniention applied to a propagating frame, an.

Figures 3 and 4 are, respectively, a part sectional plan and a liront'` elevation show-v ing theinvention applied to. a foster mother.

Referring to Figures 1 and 2` of the drawing, l is the body of the propagating fra-me xav-ing ends 2 and 3 and partitioned 5 which divide the frame intQthree com partments, .6, 7 and 8 ofA substantially equal dimenfsons, Preferably each compartment is covered separately by a hinged glazed roof .9.` The heating unit comprisesvthree flat rectangular tanks 10, 11j and 12, arranged end to end and having their interiors eommunicating with one another, the unit 10 at oneend `being largest, the next unit 11 of smaller size and thethird unit 12 of still smaller size. In the lcon# struction illustrated the heating unit inserted lengthwise of; the frame, openings being'- i'ormed. in the end 2 and in the partition 4 large enough for the passage therethrough of the largest element 10 and. the partition 5 having an opening large enough to` receive the end of element 11. j

The heating unit liesl upon or close 'to the bottom ofthe trame and,.when in position, the` largest element thereof covers praetioally the whole of the. door` of compartment 6, the second element 11 covers a par-t of the floor of the compartment 7 and the third element 1 2 a still smaller part of the floor of compartment 8.

From element 10 a small extension. 14 prof jects outside the frame under which is placed Sialtablel heating means, for example, an Oil lamp. The? eXtenSion 14. has in itefupper side a plug hole 15 through which the heating unit can be l'illed with water. When the lamp is lighted and placed in position under the extension 14 all of the water in the heating element is warmed. and the units 10, 11 and 12 heat their respective compartments 6, 7 and 8 approximately in proportion to the area of their radiating surfaces. A vent 16 (Fig. 1) may be provided at the end of the smallest unit; and said unit may also have a drain plug 33 through which the heating unit may be emptied when desired.

Instead of an oil lamp a gas burner or other source of heat may be employed.

and 31 are trays provided in each of the compartments, the lower one of which may, for example, have a bottom of wire mesh upon which damp moss or other suitable material is placed. The upper tray 31 carries the seedlings or the like. In the case of compartments 6 and 7 the trays rest upon the heating element, but in compartment 8 supporting members 32 (Fig. 1) are provided.

Where the invention is applied to a foster mother, as shown, for example in Figures 3 and 4, the heating unit consists of two elements 17 and 18, the larger element 17 as in the case of the propagating frame justdescribed, being inthe form of a large flat rectangular tank. This element covers substantially the whole area of the. rst compartment 19 of the foster mother, but in this case it is arranged in the upper part of the compartment so as to throw the heat downward. The other element 18 of the heating unit may bein the form of a pipe or cylinder which extends through the partition 21 between the two compartments 19 and 20, the difference of temperature in the two compartments being in this case very much more marked than in the case of the gardenpropagating frame. The water, as in the case of the propagating Jframe, is heated by means of a lamp or other source of heat placed beneath an extension 22 of the rst heating element 17.

For the purpose of removing the heating unit the partition 21 is preferably formed in two parts, the upper half above the pipe 18 being readily removable by sliding it upward from between parallel vertical slides 28. 24 is the usual drawer for affording ready access to the very young chicks or the like within compartment 19, and 25 is a window permitting observation of the interior of compartment 20. Doors 26, 27 are formed in the side of drawer 24 and partition 21, respectively, to permit the transfer of the chicks from compartment 19 to compartment 20.

Instead of the heat being distributed in the several compartments by water in the tanks, the desired elect can be obtained by heating the air in the heating unit, the construction of the latter remaining substantially the same as when water isr used.

I claim:

1. Means for heating structures having` a plurality of compartments side by side which are required to be kept at different temperatures, comprising a heating unit adapted to be inserted in and removed from the structure and composed of a plurality of integrally-formed communicating heating elements disposed in longitudinal relation and of different dimensions to present different heat radiating areas, each of said elements adapted, when the unit is inserted in the structure, to lie within and to heat a different compartment of the structure.

2. Means for heating structures having a plurality of compartments side by side which are required to be kept at diti'erent temperatures, comprising a heating unit adapted to be inserted in and removed from one extremity of the structure longitudinally ofthe latter and composed of a plurality of water-containing communicating heating elements arranged in endwise relation, one of the end elements being in the form of a flat tank, said elements each presenting a. different heat radiatingtarea and each adapted to lie within and to .heat a different compartment of the structure.

3. Means for heating structures having a plurality of compartments side by side which are required to be kept at different temperatures, comprising a heating unit insertable in one extremity of the structure to extend longitudinally of the latter, said heating unit being composed of -a plurality of communicating heating elements one of which is in the form of a fiat tank, said elements successively decreasing in dimensions to present different heat radiating areas and each adapted to lie within and to heat a different compartment of the structure, the element of greatest heat radiating area having an extension adapted to extend outside the structure and to be heated by a source of heat external to thestructure.

In testimony whereof I have hereunto set my hand.

CLARENCE HANCOCK.
